26fun的第2塊線路板已經出現soic to dip鍍金版

admin

每一個玩diy的朋友 當然也一定會用到soic 轉 dip的convertor 去試一試不同opamp出來的效果分別

但竟然發現無論是台灣、大陸，香港還是遠至美國、歐洲diy所用的轉版設計也很有問題,

說真的，完成不明白他們如何可以將自己的音響輸出質素講到天馬行空，評論別人的產品也好像頭頭是道, 更有一班忠實fans講乜信乜，但竟然連影響聲音最重要的心臟, 連接pcb最基本設計這麼簡單只有幾條線路也像幼稚園的水平   

以下是在網上搜得的soic dip轉版也存在以下問題：

1. 走線太幼, 電流大一點也不知如何應付. 如何可以大動態呢
2. 整板過孔via太多而且沒有必要
3. 走線與走線之間平行 而且太接近, 避免干擾最小也要有2倍線寬 (最基本的電子學也有教)
4. 走線沒有必要的走長
5. 其中一個大陸設計更驚人在走線需要最短情況下竟然引出一大面積的銅用來接收周圍的干擾後會更好聲嗎

找了一整天, 最後只係得啖笑,
附合以上所有要求的只有一個美國設計就是epb的那一個,
但這個soic的底部就是針位應該很難安裝而且也沒有必要的大塊,

最後當然又要攪攪佢, 26fun的第2塊線路板也將會因此出現
相信所有對音質有真正要求的diyer也要將手上的轉版全部更換

1. unnecessary via (inductance problem in the signal path)
2. long and parallel copper trace routing (interference problem)
3. unnecessary long trace (signal degrade problem)
4. narrow and thin copper trace (small current tranfer limit)

Replace all your current soic to dip adapter NOW and see the different!
